  1. 1. Exosomal Shuttle RNA

    Författare :Karin Ekström; Göteborgs universitet; []
    Nyckelord :exosomes; exosomal; shuttle; RNA; esRNA; vesicles; mast cell; gene transfer; microRNA;

    Sammanfattning : Exosomes are small membrane nanovesicles of endocytic origin that can be released by many different cells to the extracellular environment. Exosomes have been found in a number of body fluids such as blood plasma, breast milk, bronchoalveolar lavage fluid and urine, indicating relevance in vivo. LÄS MER

  3. 2. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria

    Författare :Mirthe Hoekzema; Gerhart E. H. Wagner; Magnus Lundgren; Kai Papenfort; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; small RNA; sRNA; non-coding RNA; Hfq; gene regulation; post-transcriptional regulation; biofilm; OmrA; OmrB; toxin-antitoxin; TisB; IstR-1; Persisters; CRISPR-Cas; CRISPR-Cas adaptation reporter; Escherichia coli; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). LÄS MER

  4. 3. Small RNA-mediated Regulation of Gene Expression in Escherichia coli

    Författare :Cecilia Unoson; E. Gerhart. H Wagner; Renée Schroeder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small RNA; non-coding RNA; antisense; translational control; ribosome standby; toxin-antitoxin; IstR; TisB; tisAB; MicF; Lrp; Microbiology; Mikrobiologi; Cell and molecular biology; Cell- och molekylärbiologi; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Non-coding RNAs are highly abundant regulators of gene expression in all kingdoms of life that often play important roles in vital cellular functions. In bacteria, small regulatory RNAs (sRNAs) usually act post-transcriptionally by regulating mRNAs through base pairing within ribosome binding sites (RBS), thereby inhibiting translation initiation.

  5. 4. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs

    Författare :Erik Holmqvist; E. Gerhart H. Wagner; Udo Bläsi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small RNA; sRNA; non-coding RNA; antisense; gene regulation; post-transcriptional regulation; translational control; outer membrane protein; OmpA; MicA; biofilm; flagella; curli; bistability; Lrp; MicF; CsgD; FlgM; OmrA; OmrB; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. LÄS MER

  7. 5. Structure of small RNA phages

    Författare :Kaspars Tars; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; bacteriophage; MS2; virus assembly; structural evolution; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Small RNA phages belonging to the family Leviviridae are among the simplest known viruses. They have been used extensively as models for studies of various problems in molecular biology, including protein-RNA interactions, repression of translation, virus assembly and virus evolution.
